New Zealand sports fans are being called upon to get their creative juices flowing and help design the official uniform for the Kiwi Olympic team at next year's Games in London.

The New Zealand Olympic Committee will today launch a competition asking fans to submit their ideas for the team's official t-shirt.

The date of the launch marks 365 days until the Games get underway in London on July 27, 2011.

New Zealand women's Black Sticks Samantha and Charlotte Harrison and the fashion design team at World in Auckland have already submitted entries into the national competition and are hopeful their compatriots will follow suit.

"It's like everyone supporting each other," Charlotte said of the competition.

The NZOC will also announce today the results of an online poll which has revealed the Olympic uniform most favoured by Kiwis.

The Athens 2004 uniform, which featured a white fern reminiscent of a Greek laurel wreath, came out ahead of the uniforms worn at Rome 1960, Seoul 1988 and London 1948.

The New Zealand team's chef de mission Dave Currie, who will leave for London today for his second Olympic site visit, said designing part of the team uniform was a big responsibility.

"We know the uniform means a lot to the athletes, and it means a lot to New Zealanders," he said.

"We're asking all New Zealanders to get creative and make the team proud at London 2012."

During his fleeting visit to London, Currie will attend a number of test events designed to check venue functionality ahead of the Olympics next year.

He will join New Zealand athletes and support teams at the Junior World Rowing Championships on the Olympic course at Eton Dorney, the Weymouth and Portland International Regatta 2011 and the ITU World Series Triathlon test event at Hyde Park.

A team of around 200 athletes is expected to represent New Zealand in 17 sports at next year's Olympics.
